Abstract

PURPOSE:To assure a high magnetic flux density without decreasing the area of flow passages by juxtaposing plural planar permanent magnets via spacing control means in such a manner that the surfaces facing each other have different poles to form permanent magnet arrays and using the spacings between the respective permanent magnet arrays as the flow passages. CONSTITUTION:The fluid introduced from a fluid introducing part 32 of a casing 30 is passed to the spacings between the permanent magnets 21 formed as a part of the flow passages. The fluid is thereby magnetically treated during the passage through the spacings between the permanent magnets 21 and the magnetically treated fluid is discharged from a fluid discharge path 33. The spacing between the permanent magnets 21, i.e., the width (d) of the flow passages is set by the spacing control means (spacers) 22 at about the size at which clogging does not arise according to the viscosity of the fluid to be treated and the sizes or particle sizes of the dust and the like contained therein. Since the permanent magnets 21 are formed to a planar shape, the magnetic treatment is executed over the entire region in the longitudinal direction where the fluid passes, even if the above-mentioned spacing is widened. The time for the magnetic treatment is thus prolonged and the sufficient magnetic treatment is executed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic treatment device that magnetically purifies wastewater and improves water quality, for example, and particularly relates to a magnetic treatment device suitable for treating a large amount of wastewater. It relates to a processing device.

[Conventional technology]

Magnetically treated water has the effect of preventing and removing red rust and scale in drinking water or on the inner walls of pipes, promoting plant growth,
It is known to have the effect of settling suspended solid particles, improving the performance of concrete, and improving the fuel efficiency of liquid fuel, and various devices for magnetic treatment are also known.

One of them is a water treatment device disclosed in Japanese Patent Application Laid-Open No. 59-154188. This water treatment equipment has a plurality of cylindrical permanent magnets whose inner and outer circumferential surfaces are formed with different polarities in a cylindrical space formed by an inner jacket and an outer jacket made of non-magnetic material. A central member made of a ferromagnetic material and having an outer diameter smaller than the inner diameter of the inner jacket is placed in the center of the inner jacket. an outer tube made of a ferromagnetic material and having an inner diameter larger than the outer diameter of the outer jacket is concentrically covered with the outer jacket. An outer flow path is formed between the outer jacket and the outer jacket, and the treated water is configured to flow through the inner flow path and the outer flow path.

With this configuration, the lines of magnetic flux emitted from the cylindrical permanent magnet are made to cross the inner flow path and the outer flow path,
It describes the effect that the treated water flowing in the above-mentioned inner and outer channels can be exposed to the maximum magnetic field.

Another known example is a drinking water treatment device disclosed in Japanese Patent Laid-Open No. 61-33290. In this drinking water treatment device, a plurality of hollow disc-shaped permanent magnets magnetized in the axial direction are arranged coaxially and in close contact with each other so that the same poles are in contact with each other in a hollow cylindrical body θ1, and the hollow part allows drinking water to flow. The drinking water flow path is formed in a flow path that allows water to pass through the drinking water flow path, and the flow path surface of the drinking water flow path is coated with a non-magnetic material. With this configuration, the magnetic fields are mutually compressed, and the flux density perpendicular to the flow can take the maximum value, and since the fluid passes through the inside of the hollow disc-shaped permanent magnet, the magnetic flux does not expand inside and It is stated that the space has an effective θ-branched acousticity over the entire area, and that the fluid can be activated effectively and the reforming function can be performed without the proliferation of bacteria or other bacteria.

Furthermore, as another embodiment, the magnetic treatment is performed by causing the treated water to flow through a flow path consisting of a cylindrical body formed between an inner tube connected to different poles of a permanent magnet and an outer tube surrounding the outer circumferential side of the inner tube. There is a water treatment equipment that does this. In this water treatment device, a gap is formed by bringing an inner tube and an outer tube close to each other at one end of the flow path, and a high magnetic flux density is generated at the gap, and when the treated water passes through this gap, the treated water It is set to undergo magnetic treatment.

[Problem to be solved by the invention]

By the way, in the water treatment device mentioned first, lines of magnetic flux are generated between a permanent magnet with an inner N pole and an outer S pole, and a permanent magnet with an inner S pole and an outer N pole adjacent to the permanent magnet in the axial direction. The magnetic flux lines cross the entire surface of the annular cross sections of the inner flow path and the outer flow path, but the distance between the different lines becomes longer, so the magnetic flux density becomes smaller and the efficiency deteriorates.

In addition, in the second drinking water treatment device, since the same poles are connected in series so as to be in contact with each other, the repelling magnetic field causes demagnetization, making it unsuitable for long-term use.

Furthermore, in the third mentioned water treatment equipment, the gap part is il! Although it is magnetically treated when the object is exposed, it is instantaneous and it is difficult to say that the magnetic treatment has been applied sufficiently. Further, since the flow path area becomes smaller in the gap portion and the flow path resistance increases, it is difficult to secure a desired flow rate.

In addition, in any of the conventional examples, since the object to be treated is a relatively low viscosity liquid such as drinking water, the cross-sectional area of the magnetic action path for performing the magnetic treatment must be made small. However, if the cross-sectional area of the magnetic action path is made small in this way, it will quickly become clogged with waste water that contains a large amount of dust, such as waste water, or fluids that contain many particles such as conic rete. Therefore, it cannot be put to practical use.

This invention is 8. This was done in view of the above technical background, and its purpose is to provide a magnetic processing device that can ensure high magnetic flux density without reducing the flow path area and can demonstrate reliability over a long period of time. It's about doing.

[:1! Means for Solving the Problem] In order to achieve the above object, the present invention provides a magnetic processing device that is installed in a fluid path and performs magnetic processing by introducing fluid into a magnetic field, which includes a plurality of plate-shaped permanent magnets. A permanent magnet array is formed by arranging the permanent magnets in parallel with each other through a spacing regulating means so that the opposing surfaces thereof have different polarities, and a fluid introduction part and a fluid discharge part, and between each permanent magnet of the permanent magnet array. It has a structure including a casing that accommodates a row of permanent magnets using the gap as a flow path.

[Effect]

In the above means, a plurality of plate-shaped permanent magnets are arranged side by side through a spacing regulating means so that the opposing surfaces thereof have different polarities to form a permanent magnet row, and this permanent magnet row is housed in a casing. , the fluid introduced from the fluid introduction part is caused to flow through the gaps between the permanent magnets formed as part of the flow path, so that magnetic processing is performed when passing through the gaps between the permanent magnets. Fluid is discharged from the fluid outlet.

At this time, the gap between the permanent magnets, that is, the width of the flow path, should be set to a size that does not cause clogging depending on the viscosity of the fluid to be treated, the size of the included dust, or the particle diameter. It can be set by In addition, even if the gap between the permanent magnets becomes wide, since the permanent magnets are formed in a plate shape, magnetic processing is performed over the entire length of the magnet, and the magnetic processing time becomes long. magnetic processing becomes possible.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The drawings are all for explaining a magnetic processing device according to an embodiment of the present invention, and FIG. 1 is a partially sectional perspective view of the magnetic processing device, FIG. 2 is a perspective view showing the entire magnetic processing device, and FIG. FIG. 3 is a perspective view of the permanent magnet array, and FIG. 4 is an explanatory diagram showing the flow of fluid.

In FIGS. 1 and 2, the magnetic processing device 10 mainly includes a permanent magnet array 20 and a gauging 30 that accommodates the permanent magnet array 20.

As shown in FIG. 3, the permanent magnet array 20 is formed by arranging a plurality of permanent magnets 21 in parallel with a spacer 22 made of a non-magnetic material serving as a spacing regulating means interposed therebetween.

This permanent magnet 21 has a substantially rectangular plate shape, and both sides thereof are formed into N and S poles, respectively, so that the mutually opposing surfaces of adjacent permanent magnets 21 have different polarities and are approximately parallel to each other. It is located. Further, the end faces 23 on the upstream and downstream sides of each permanent magnet 21 in the flow direction are chamfered to reduce flow resistance.

The length of the spacer 22, that is, the distance d between adjacent permanent magnets 21, is determined depending on the type of fluid to be treated. This interval d is narrow when the fluid to be treated is, for example, drinking water or cultivation water, and widened when it contains rough particles, such as wastewater or concrete.
i: Set in the range of 1 mm to 5 mm. As a result, a magnetic flux density of about 3000 to 8000 Gauss can be obtained with a 10800 Gauss permanent magnet.

The casing 30 has a permanent magnet side storage section 31 with a front-shaped cross section.
It is made of a magnetic material and includes a fluid outlet 32 having a circular cross section and a fluid outlet 33 that communicate with the permanent magnet side storage part 31. These fluid 4 ports 32 and fluid outlet 3
3 has threads 42° and 43 cut on its outer periphery, and is intended to be able to be connected in the middle of piping. Furthermore, glass 3 is provided in the frame 34 on the upper and lower surfaces of the permanent magnet side storage section 31.
A viewing window 36 into which a lens 5 is fitted is removably attached with bolts 37, so that the inside of the rung 30 can be viewed through the glass 35.

In the magnetic processing device 10 constructed as described above, the length of the spacer 22 is selected depending on the fluid to be processed;
Since the width of the storage section 31 is determined, the number of permanent magnets to be arranged in parallel is also selected based on this. In this way,
The permanent magnet array 20 whose spacing d and number have been selected is pushed into the permanent magnet storage section 31 of the casing 30 through one of the removed viewing windows 36, and each permanent magnet 21 is inserted into the storage section 31.
The permanent magnets 21 at both ends are arranged parallel to the side wall 38 of the side wall 38 so that the permanent magnets 21 are in contact with the inner surface of the side wall 38. As a result, the flow path formed by the gap between the permanent magnets 21, that is, the n-air action path 24, becomes approximately parallel to the flow direction. Also, as shown in FIG. The longitudinal position of the stone row 20 is regulated at 40 by the side wall section, and the longitudinal position of the stone row 20 is regulated by the longitudinal force from the fluid to be treated. It is also intended that no misalignment will occur.

When the permanent magnet array thus positioned is placed at a predetermined position, the frame 34 of the viewing window 36 is attached to the upper surface of the casing 30 via the backing 39, and the bolt 37 is tightened. As a result, the end surface 25 of each permanent magnet 21 comes into contact with the surface of the glass 35, and the fluid always passes through the magnetic action path 24 between each permanent magnet 21.

Assuming that the magnetic processing device 10 configured as described above is attached to the fluid pipe through the screws 42 and 43, and a fluid to be processed, for example, drinking water, is introduced from the fluid introduction port 32,
As shown in FIG. 4, the fluid passes through a magnetic action path 24 consisting of gaps between the permanent magnets 21 of the permanent magnet array 20, and during this passage, the fluid is magnetically treated and discharged from the fluid outlet 33, and is supplied to a predetermined supply. It is supplied to the hem. Therefore, the fluid is sufficiently magnetically treated while flowing in the longitudinal direction of the magnetic action path 24.

Furthermore, while the fluid flows through the magnetic action path 24, dust and the like contained in the fluid may clog the magnetic action path 24, causing the magnetic action path 24 to become clogged. Since it is possible to see through the glass 35 of the window 36, if the clogging becomes severe, the viewing window 36
It is also easy to remove and clean. At that time, if the diameter of the dust particles included in the flowing fluid is large,
It is also possible to freely widen the interval d between the magnetic action paths 24 by replacing the spacer 22, and the optimum magnetic treatment can be selected by looking at the condition of the target fluid.

By the way, when magnetic treatment of wastewater is performed using the above embodiment, there is an effect of accelerating the precipitation of impurities and foreign substances, and if the sedimentation rate of wastewater before treatment is 1, it is about 20
It has been experimentally found that the sedimentation rate increases by about 30% and that water purification effects can be obtained within a known period of time.

In the above embodiment, the viewing window 36 is provided on both the upper and lower surfaces of the casing 30, but it goes without saying that it may be provided only on the - side. However, from the viewpoint of visibility of the fluid and the magnetic action path 24, it is preferable to provide them on both sides.

In addition, the above-mentioned magnetic treatment device 10 can perform various known magnetic treatments such as removing red rust and scale, purifying wastewater from garbage disposal sites, strengthening concrete, purifying drinking water, and promoting the growth of plant cultivation. Needless to say, it can be applied generally.

As described above, according to the above embodiment, (1) it is possible to obtain the magnetic action path 24 with any gap by simply changing the spacer 22, and it is possible to easily select the optimum gap d for the target fluid; ■ Also, magnetic action path 2
4 is set almost parallel to the flow path, and the interval d can be made wide, so it can be applied to fluids with high resistance or fluids containing large particles without causing pressure loss.
The processing efficiency is also high. ■ The magnetic processing area is very large because it corresponds to the product of the area of one side of the opposing permanent magnets 21 and the number of permanent magnets 21.
In addition, since magnetic processing is performed over the entire length of the fluid passing through it, efficient magnetic processing of a large amount of fluid is possible. Yes, ■ Since a magnetic field is formed by having different poles facing each other, there is no risk of demagnetization, and stable magnetic processing is possible over a long period of time.

〔Effect of the invention〕

As is clear from the above description, according to the present invention configured as described above, a high magnetic flux density can be achieved without particularly reducing the flow path area, and a high-performance magnetic field that can demonstrate reliability over a long period of time can be achieved. A processing device can be provided.
